APPARATUS FOR USE IN ATTAOHING HEELS.

Application filed January 25, 1923. Serial No. 614,803.

To (ZZZ "whom itmay concern:

Be it ,known that I. FREDERIC E. B ns- TRAN D, a citizen of the United States, residing at Lynn, in the'county of Essex and State of Massachusetts, have invented certain Imence characters on the drawings indicating like parts in the several figures. This invention relates to attachingheels to shoes, and is illustrated as embodied in improvedmeans for use in clamping a heel against the heel seat of a shoe while the heeLattaching adhesive is ,drying.

In my co-pending application Serial No. 561,901, filed May 18, 1922, there is described apparatus for clamping heels to lasted shoes bypassing a headed screw fastening through a perforation in the rear end of each last and through the heel seat of the shoe. into the heel, in such a manner asto clamp the last and shoe and heel together. An object of the present invention is to provide for clampingheels in a generally similar manner to shoes from which the lasts havebeen removed without rendering it necessary to replace the last in the shoe.

From this, point of view the invention may be regarded as. contemplating the use of blocks, eachof which has a surface shaped to engage and transmit pressure to,

the inside rear bottom surface of a shoe, opposite the heel seat, and each of which is formed, with a reduced portion having fastening-receiving hole or perforation, said reduced portion being adapted loosely to be, received within, a shoe so that ample clearance will be provided for the conven-. ient introduction and removal of the block and adapted wholly to be contained within the shoe so that it will not interfere with the free manipulation of the shoe in the performance of finishingoperations thereon while the heel is temporarily clamped to the shoe by thescrew fastening. Preferably a pressure-receiving portion, used in clamping the block against the shoe and heel while inserting the fastening, is arranged to receive pressure directed perpendicularly toward said surface, in such a manner that the pressure may be applied without obstructing the fastening-receiving hole. A

shoe

thimble hole may be provided, if desired,

to receive the usual jack pin, in supporting the shoe on a rack or for other purposes,

(lther objects and features of the invention, includingzthe specific construction of the blocks, and a novel heel-supporting device, will be apparent from the following description of an illustrative embodiment of the invention shown in the accompanying drawings, in which Figure 1 is a side elevation,

showing the work partly in section, of a block and a anda heel clampedtogether and resting on the novel heel-supporting device; Fig. 2 is a top plan view of the assembly shown in Fig; 1 without the shoe; and

Fig. 3 is a side elevation of a modified form of block and a correspondingly modi- .fiedform of pressing member.

As shown in thedrawings, the novel block 10 is held assembled with a shoe 12 and a heel 142, ina machine generally like that of my prior application, by the clamping action of asupport l6 and a pressing member 18. "While the block and shoe and heel are so held, and after a hole is drilled through the heel seat of the shoe into the heel, a. screw fastening 20 is passed through a hole or perforation 22 in the block and through the heel seat of the shoe into the heel. The screw :lastening 20 comprises a screwthreaded shank carrying one or more washers 9A: of leather or other resilient material and one or more metal washers 26, the shank being looped at one end into the form of an eye. The washers 24: and 26, together with the looped end of the screw shank, may be regarded as constituting the head of the fass tener. Clamping pressure is transmitted from the looped end of the fastening through the one or more resilient washers 24 and the metal washers 26. After the drying of the heeleattaching adhesive, fastening 20 and block 10 are removed.

A. notch 28 may be formed in the block L0 to receive the pressing member 18 with: out permitting it to slip, and without obstructing the hole throughthe block. or if preferred, a thimble hole 30 may be formed in the block to receive a jack pin, and, a steel wear plate 32 may be provided to be engaged by a toothedpressing member 34 (Fig. Prongs 36 are carried by the bot tom of the block, to prevent slippage.

The top of a heel isalmost invariably concave, and the bottom of block 1.0 is formed substantially plane, so that the maximum pressure is localized in a narrow area .about the periphery of the heel and shoe, closing any gaps in the rand crease and producing a very close fit. The bottom flange 38 of the block is of a general D shape, corresponding to the shape of the inside rear bottom surface of a shoe.

The improved support 16 shown in the drawings comprises a base at) having a post 412 to be clamped in the frame of the machine ;shown in my prior application, and having a surface to engage the tread surface of a heel. At the center of its rear end a sleeve 26 is formed, in which is clamped by set screw 48 apost5O carrying a leather, rubber, or felt insert 52 to engage and support the rear surface of the heel.

Sleeves 54 are formed at opposite sides of the support, in each of which is clamped by a set screw 56 a shaft 58. Each shaft 58 serves to support a U-shaped arm 60 having a pair of bearings (32 turning on opposite ends of the shaft. These arms are urged toward one another by a spring 641- as far as permitted by an adjustable stop 66 carried by one of the arms. The end of each arm 60 is formed as a split clamp, in which is adjustably held a vertical post 68 having a heel-engaging insert 70.

in operation, a block 10 and shoe 12 and heel 1% are held assembled together by supporting the heel on the support 16 and applying pressure through member 18, a hole isdrilled through the heel seat of the shoe into the heel in alinement with hole 22, and a fastening 20 is inserted and driven home. The shoe may now be handled and treated in any desired manner, the block and shoe and heel being held clamped together by fastening 20. After the heel-attaching adhesive has dried, fastening 20 and block 10 are removed, the heel nailed, and the shoe finished in any desired manner.

While specific embodiments of my invention are illustrated and described, it is not my intention to limit its scope thereby or otherwise than by the terms of the appended claims.

I claim:
